Last thursday I worked with Kees on our 3D printer. It was long overdue because I have been busy working... Until wednesday we had a machine that was moving. We could give some commands, and the machine would move to the designated coordinate.
A few weeks back I had ordered an extruder because making one ourselves would take too long. Thursday we connected it to the electronics and after some modifications in the firmware we could see the extruder nozzle heating up, we could see the temperature, and the stepper motor driving the extruder moved. We only lacked filament.
A friend of Kees had an extruder and 3mm PLA material. So with this we could try to extrude. See below the result... Next week we'll get the steps per mm filament correct and I hope we'll be able to print something then more sophisticated. We're nearly there.
